Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00013 | $0.00403 |
| Opus 5.5 | $0.00005 | $0.00161 |
| Sonnet 5.5 | $0.00003 | $0.00081 |
| Haiku 4.5 | $0.00001 | $0.00040 |
Grade A, and why
init scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
/mobile-spine:init
Run the mobile-spine:init skill bundled with this plugin: a 6-question interview that scaffolds a mobile-spine workspace. The scaffold writes workspace-owned data only — CLAUDE.md, SETUP.md, README.md, LICENSE, .gitignore, .claude/settings.json, .claude/mobile-spine.config.yaml (from the interview), .claude/commands/feat.md (thin stub → /mobile-spine:feat), _context/operations.md, and .gitkeep placeholders under _context/api/, _context/design/, _tasks/.
The five subagents (api-agent, pm-agent, android-agent, ios-agent, docs-agent) and the full /feat / /feasibility command logic are not scaffolded — they're plugin primitives served globally from plugins/mobile-spine/agents/ and plugins/mobile-spine/commands/. /plugin marketplace update claude-code-mobile-spine propagates updates to them automatically.
The skill body lives at ${CLAUDE_PLUGIN_ROOT}/skills/init/SKILL.md — read that file first and follow its instructions verbatim. The skill resolves the templates directory via ${CLAUDE_PLUGIN_ROOT}/skills/init/templates/, interviews the user, applies the (now-reduced v2.0) substitution scope to the doc templates, writes .claude/mobile-spine.config.yaml from the interview answers, and scaffolds to the chosen install location.
Important: do not deviate from the skill's substitution rules in §4-2, the config-write step in §4-3, or the sanity checks in §4-4 — they encode the placeholder discipline that keeps the scaffold consistent across users.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

init is a command published in the GitHub repository bentleypark/claude-code-mobile-spine (1 stars, last pushed 5d ago), licensed MIT. It adds 13 tokens to every session and 403 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
